The document provides an introduction to the financial system, outlining its six main parts: money, financial instruments, financial markets, financial institutions, regulatory agencies, and central banks. It describes how each part functions within the system. It also outlines five core principles that underlie the financial system: time has value, risk requires compensation, information is the basis for decisions, markets determine prices and allocate resources, and stability improves welfare. Finally, it lists some key functions performed by the global financial system, including providing savings mechanisms, storing wealth, providing liquidity, enabling credit, facilitating payments, managing risks, and allowing governments to influence the economy.
